This invention relates to a paper dispenser and more particularly to a dispenser of. the type used in dispensing toilet paper and which automatically dispenses a predetermined quantity of pa-i per in response to actuation of a push button or the like. i

"Various paper dispensers have been designed from time to time, buteach of these have'had disadvantages in that they have been hard to- It is an object of this invention to provide a paper dispenser in-w-hich the user only as am ce ss to that portionof; the pa er which is tobe out off by the user. 'This object is accomplished by providing a dispenser in which additional paper is exposed only after the user has cut off the desired amount of paper. i

More particularly it is an object of this invention to provide a dispenser in which ressure on a spring pressed plunger" or the like first severs a predetermined quantity of paper as the plunger is pushed in and then prepares to dispense a new supply of paper astheplunger moves outwardly.

Another object of this invention is toprovide a practical dispenser which may be manufactured at a low cost. r V

Still another object of this invention isto pro-- vide a dispenser which is quiet in operation; 7

Other objects and advantages reside inthe construction of parts, the combination thereof and the mode of operation, as will becomem'ore apparent from the following description.

In the drawings:

Figure 1 is a vertical sectional view ot thedevice taken substantially on line 4 of Figure. 2, with parts broken away, so astoexpose the pa'- per feeding mechanism;

Figure 2 is a front elevational view with partsbroken away; i

Figure 3 is a side elevationalview with parts broken away; and" plyof'paper. w H H e For purposes of illustration, the invention has ,been shown as applied to a toilet paper dispenser,

whereas certain features of the invention are equally applicable for use in dispensing other types of paper and various other kinds of paper thin material. Consequently, the term paper as used herein is intended to be given-a; broad interpretation and to apply to various equivalent kindsof strip material. Likewise, the-unitshown is one thatis intended to be countersunk into a recess in the wall, whereas it is to be understood that" certain aspects of the invention are equally applicable to units which are adapted to be mounted on a flat surface;

Referring now to Figure 1 ot the drawings, reference numeral HI designates a mainframe whioh'is adapted tob'e; inserted into a recess in a wall such as the-wall [2. The frame Ill includes a rear guard H whiclr may be in the form of a strip as shown" or it may be in the form of a fully closed' casing which is adapted to be countersunk into a recess ma wall in accordance with common practice.

As'best shown in Figures- 3 and 4', a rolllof paper IT is adapted to' be' supported on a spindle F6.

carried by a movable inner frame member is which-is" hinged to the main frame I!) at 20 and is adapted to swing? out from the main frame for refillingas shown. The inner frame member H3 is provided with an arcuate paper guide wall 22 over which the free end of the paper 2 is ar rangedto-pass' as'shown;

As indicated in lfiaure 4 of the drawings; the

roll of paper is mounted- 0a the spindle: It with the free end 2i of the; paper overlying the arcuate" guide wall 22. In refilling' the-dispenser, the new roll of paper is simply laid in place with the" free end hanging down as ShOWI-i.- The paper feeding and cutting mechanism is carriedby' the outer movabIe frame or covermemb-e'r 24 which is hinged to the main frame ['0 at-ZE." The outer frame or cover" member 2 1 is provided with side flanges 25 which project into themain frame: [91 The cover 24 serves to'conceal tlie main supply of paper and serves toboth enclose and support the paper feeding and cutting mechanism.-

As best shown inliilgurel of the drawings; the main operator 29 for'the paper feeding and cut ting. mechanism comprises a sheet" metals-tamping which includes a push button or pushbar portion 28 which projects forwardly" at the bot-' tom edge of the cover 24; .The operatcr'zil i's hinged to the outer frame or cover 24 by means of the hinge pin 30 which also supports the cam 58 which will be described hereinafter. The portion 28 has a serrated paper cutting edge 32 formed along its bottom edge. The serrated paper cutting edge 52 cooperates with a complementary serrated cutting edge 34 provided at the lowelr end of the paper guide 22 as shown in Fi ure In order to hold the paper during the cutting operation, there has been provided a paper gripping crossbar or brake 35 which is mounted on the lower end of a spring leaf 38 secured to the inner surface of the operator 29. This crossbar moves with the operator 29 and serves to clamp v the paper against the serrated cutting edge 35 as pressure is applied to the button or bar 28 so as to firmly grip the paper during the cutting operation, thus serving as a brake. The mechanism for feeding the paper is designed so as. to feed a new supply ofpaper'as the operator 23 moves out rather than when the operator moves in as is the usual practice. The main operator 25 is biased into its full line'position, as shown in Figures 1 and 3, by suitable spring means such as the blade spring 45] (see Figure 3) which has its upper end welded or otherwise secured to theinner surface of the'cover 25 and has its lower end pressing against the inner surface of the operator 29. The paper feeding mechanism comprises an arm or lever 53 which is adapted to rotate or oscillate about a pivot pin 52 which is fixed to the side flange-25 of the cover 24. The outer endof the arm to isbent over, as shown in Figure 2, and pivotally supports an elongated rubber finger or paper feeder 54. The arm 59 carries a roller 56 which cooperates with an operating cam element 58. The camelement 58 is secured to the hinge element 59 which in turn is pivotally supported on the hinge pin 39. The cam element 58 is adapted to bemoved from its full'line position shown in Figure l to the dotted line positionby means of the cam element Gilwhich is secured directly to the operator 29 and which supports a pair of rubber buffers 62 in sucha manner that there is a lost motion connection between the cam element'58 and the operator 60.. A compression coil spring 6| is arranged as shown for preventing rattling and for urging the operator 29 to move away from the hinge element 59. As pressure is applied on the operator 28, the element 6!) acting through the lower buffer 52 willshove the cam element 58 upwardly so as to move the paper feeding arm 59 from its full line position into its dotted line position. The weight of the depending portion of the finger element 54 plus the weight of the overhanging end 55 of its supporting shaft tend to cause the element 54 to' normally hang downwardly as shown in Figure 1. During the first portion of the upward movement of the arm the paper feeding element 54 does not contact the paper whatsoever and when the arm 55 approaches its upper position, the corner of the element 54 lightly rides over the paper without moving the paper. As the element 54 approaches its upper position, the paper-clamping crossbar or brake 33 will have moved into paper clamping position and will prevent the paper feeding element 55 from feeding the paper in the wrong direction. However, when pressure on the push bar 28 is released, the spring 40 will begin to return the parts to their full line position and as the parts thus return, the paper'gripper 54 will feed a predetermined quantity of paper from the roll 5 Figure 1.

of the spring 64 also assists in forcing the cam 7 element 58 to return to its full line position once the roller 55 rides over the peak point on the cam element 58.

The relationship between the center of rotation of the arm 5!! and the curvature of the paper guiding wall 22 is such that the gripper 54 loses its grip on the paper at the end of the paper feeding movement. By virtue of the above described arrangement, it ,is obvious that a new supply of paper is fed down as the push bar 28 andoperator 28 return to theinnormal. position and that thehuser can pull out any additional amount of paper he wishesbefore :pressing on the operating bar-28" for severing the paper. The

amount of paper automatically fed down by the dispenser is largely determined by theshape and arrangement .of the..cam element, '58 and the design is preferably such. thatfthe desired 7 amount of paper is automatically fed down whereby it is notn'ecessary to exert any further pull on the paper. V

Although the preferred jembodirnent of the device has. been described, it will be understood that within the purview of thisinvention various changes may be made in the form, details, proportion and arrangementof parts, the combination thereof and mode ofoperation, which generally stated consist ina device; capable of carrying out theobjects set forth, as disclosed and defined in the appended claims.
